Does pentax have any macro zoom lens?

Answer 1

The term "macro zoom" is misleading. They should be labeled "close focusing".

A real macro lens is one specifically designed for sharpness at close focusing distances. It has a "flat field" of focus for photographing stamps or old photographs or other flat objects. A true macro lens will also give you a life-size image, aka 1:1 reproduction ratio.

The true macro lens is optimized for center to edge sharpness and has minimal light fall-off from center to edge.

A zoom lens with "close focusing" capabilities has none of the attributes of a true macro lens. A "close focusing" zoom will usually give you only a 1/4 life size image, aka 1:4 reproduction ratio. This is not to say that you can't take some nice images with a "close focusing" zoom because you can.

Pentax offers a full line of zoom lenses with "close focusing".

Answer 2

For their DSLR, they must to be competitive. They USED to long ago when Asahi made the Spotmatic.

The Spotmatic was a great camera with a lousey screw on lens, but it was a great camera.

Until the AE-1 came long from Canon NEWS photographers who couldn't afford NIKON F's bought Spotmatics and they had a FULL COMPLIMENT of lenses.

Oh, you said ZOOM NO ONE makes a MACRO ZOOM. It violates the rules

A MACRO is a flat field medium telephoto, often an 100mm.

ZOOM loses resolution at the edges

So NO

It's fixed lens if anything.

If you are looking for a ZOOM that MACROS get used to SOFT EDGES just like a set of DIOPTER lenses!
